SOURCE: air not blowing out top dash vents

Just posted my suspicions elsewhere:

The baffles that direct air, heated or cooled, are controlled by vacuum 'motors.'
You may have a vacuum line off somewhere or the vacuum reservoir is cracked or one of its connectors (thin plastic protrusions) is broken.

SOURCE: dash vents not working

It may be the actuator not working properly. Should be above the accelerator pedal to the right.

SOURCE: Dash vents will not blow air

It may be the mode actuator. Have you heard any clicking or other strange noise ? Under the drivers rear seat, in a plastic box is a fuse panel. Remove the two retainers, and the cover. Remove the HVAC or A/C fuse for a minute or two. Reinstall the fuse and this will make the A/C system relearn. Whwn you put the fuses back do not touch the A/C controls. Start the truck and leave it run for two or three minutes. Then try to change the vent from floor to vent and defrost. If this does not work you will need a mode motor. Good Luck

SOURCE: Dash vents will not blow air. Defroster and floor vents blow fine.

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

Air not blowing out of the vents of my 2003 Dodge Durango


From what I hear it is a vacuum line issue. Mine is doing the exact same thing. So, I am going to get a diagram and try checking the vacuum lines to see if any are loose or tore

I go under the dash and feel the air flowing out the floor and it is coming out of the defrost, also. I noticed under the drivers side today that air is flowing and there seems to be a gap in between a part under there. There was some material stuff I saw around the edge of it that sticky brown stuff and it sometimes before came out my vents all the time. Anyways, not sure if my air is just not sealed good to blow out the vents but it is something that happened not long ago and we've not done anything under our dash area.

Dash Vents wont blow as selected


THE COMPRESSOR IS SUPOST TO RUN NOT MATTER IF IS IN HOT OR IN COLD MODE SOME TIME THERE IS A POSITION WHERE THE A/C WILL BE OFF AND THIS IS ON THE KNOB CONTROL WHERE YOU SET DEFROST AR FT VENTS
ALSO ON THE THE SWITCHING FROM DASH TO FLOOR CHECK FOR ANY VACIUM LEAKS FROM THE ENGINE COMPARMENT SINCE MOST OF TIMES THIS IS CONTROLED BY VACIUM ACTUATORS
